Question

Find the original price of a pair of shoes if the sale price is $84 after a 30% discount.

Answer 1

Explanation:

84*0.30= $25.2

84+ 25.2 = $109.2

Answer 2

Original price = $ 120

Explanation:

To find the original price given the new price and percentage discount we use the formula

`original \: \: price = (100)/((100 - x)) * new \: \: price \\`

where

x is the percentage discount

From the question

new price = $ 84

% discount = 30%

Substitute the values into the above formula and solve

That's

`original \: \: price = (100)/(100 - 30) * 84 \\ = (100)/(70) * 84 \\ = (10)/(7) * 84 \\ = 12 * 10`

We have the final answer as

Original price = $ 120

Hope this helps you
